Axle and Bearing Rating:Tapered (FN) spindles are not approved for use with 2-inch outset wheels. Parallel (FP) spindles are recommended for outset applications.O�set wheels used in a single-tire con�guration can reduce the axle beam rating and bearing life. Using inset wheels in a single-tire con�guration will not a�ect axle beam rating, but can reduce the bearing life.Using outset wheels in a single-tire con�guration moves the load point away from the center of the axle, increases the bending load in the axle, and reduces the axle beam rating and bearing life. Contact the Ridewell Engineering Dept. to determine the rating for an axle that uses inset or outset wheels in a single-tire con�guration.

Dual Wheel Calculations(S) = 2 x O(OTW) = T + S + W(ITW) = T - S - W

Axle and Bearing Rating:Tapered (FN) spindles are not approved for use with 2-inch outset wide-base wheels.

Using inset wheels in a single-tire con�guration will not a�ect axle beam rating, but can reduce the bearing life.
